"Dear Sir, — The writer was not here yesterday when your letter 
arrived. In reply we do not wish any misapprehension to aviso from our 
remark in our letter of the 7th. ^\'e mean to say that the report could in 
our opinion have only been correct if starcliy impurities had been added to 
the seed before manufacturing. — Remaining, dear sir, yours faithfully, 
" IlOBERT StEPDENSON & SON."

" Dear Sir, — Since receiving the correspondence you sent me I have 
made a fresli and careful lamination of the cake originally forwarded by 
you on February 13. ■ 
"As the result, I am able to affirm the accuracy of my report in every 
particular, and, as I have pointed out frequently, it is not the figures alone 
that mark out whether a cake is good or bad, pure or otherwise. All oils 
are not alike, nor of equal value, and an adulterated cake frequently gives as 
high or higher Jigures than a pure one. 
" To be more specihc in my remarks I affirm that the cake you sent me 
contains a great deal oi starchy material, and also foreign seeds, and among 
these foreign seeds are the following : rape, hemp, qmrry, and cotton-seed 
husk. 
*' It is not for me to say how or when these impurities got in, but their 
presence in the sample sent me I am prepared to maintain, and, if necessary, 
to demonstrate to yourself or any representative of the vendors, as I cannot 
allow my reports to be discredited in the ofl'hand way adopted by your 
correspondent. — Believe me, yonrs faithfully, 
"J. Augustus Yoelcker." 
A copy of the above letter was forwarded to the makers by 
Mr. Grundou.
